Introduction: Control Servo With Light

Hello!
In this Instructable i will teach you how to control a servo using a Photocell.
This is very simple and good for beginners.

Step 1: Materials

1 x Photocell
1 x 10k Resistor
1 x Arduino
1x Breadboard
1x Servo
and some jumpers 

Step 2: Wiring It Up

Wire everything following the schematic below.

Step 3: The Code

The Code is very simple:

#include <Servo.h>

Servo myservo;
int val;

void setup()
{
myservo.attach(12);
}
void loop()
{
val = analogRead(0);
val = map(val, 0, 1023, 0, 179);
myservo.write(val);
delay(15);
